What ring size should I use for my Bridoon?

Neue Schule has scientifically researched the difference between ring sizes and found there is no mechanical advantage between choosing a smaller or larger ring for your Bridoon. One consideration would be the size of your horse’s head. A smaller ring is probably preferable on a petite head as a larger ring would look out of place and may cause rubbing on the underside of the cheekbone or interference with the noseband. However, if the horse has the head to take it a larger ring it is acceptable to use the larger ring as a Bridoon. The larger ring is also less likely to pull through the horse’s mouth. The maximum internal diameter of the Bridoon ring has been set at 80mm by the FEI, and the Neue Schule Bridoon Bridoons are available in 55mm and 70mm ring.
